Local information disclosure via incorrect bounds check
Published Dec 16, 2022 · Updated Apr 17, 2025
An out-of-bounds read in Android kernel rild_exynos allows local users with System execution privileges to disclose information. DoSetCarrierConfig in miscservice.cpp performs an incorrect bounds check, allowing a read beyond the intended buffer. Exploitation requires System execution privileges and no user interaction; the reported impact is limited to local information disclosure.
